摘    要:在胶体化学及超分子科学领域,两亲性分子在液/固界面的聚集是一个传统而具有挑战性的课题.早在1955年,Gaudin等就推断两亲性分子在液/固界面上能形成表面胶束.但直到1995年Manne等才首次使用原位原子力显微镜(In-situ AFM)直接观察到表面活性剂十四烷基三甲基溴化铵(C14TAB)在不同的液/固界面上形成的柱状和半柱状聚集体形貌,

关 键 词:双头双亲分子  表面胶束  原子力显微镜

Abstract:A bolaform amphiphile(BP-15) bearing biphenyl group and long spacers of alkyl chains was synthesized. In-situ AFM studies indicate that the amphiphile can form two kinds of surface aggregates with different morphologies depending on solution concentration: short-range ordered cylindrical surface micelles at the lower concentration and flat domains at the higher concentration. These results agree well with the two critical micelle concentrations in bulk solution as determined by the concentration-dependent conductivity.
Keywords:Bolaform amphiphile  Surface micelle  AFM
